AimLung ultrasound (LUS) has been extensively used in the evaluation of acute respiratory distress syndrome (ARDS) in the critical care setting. In our study, we aim to assess the utility of point-of-care ultrasound (POCUS)-LUS in the initial assessment of ARDS patients presenting to the emergency department (ED).Subjects And MethodsWe evaluated a prospective convenience sample of 73 adult patients presenting to the ED. The bedside LUS was performed by the trained emergency physician on patients with undifferentiated dyspnea with a clinical diagnosis of ARDS according to the Berlin's criteria. The four major LUS findings were examined on structured 12-zone LUS. The observed profile consisted of A lines, well-separated B lines, coalescent B lines, and consolidation among patients who were clinically diagnosed as ARDS. These LUS findings may vary depending on the severity of ARDS. The findings were analyzed using IBM SPSS Statistics for Windows, Version 24.0 (IBM Corp., Armonk, NY, USA).ResultsOf the 73 study individuals, majority were male 46 (63%). The distributions of study individuals were as follows: 27% - mild ARDS, 37% - moderate ARDS, and 36% - severe ARDS. Coalescent B lines are present in about 70.4% and 92.3% of moderate and severe ARDS patients, respectively. Consolidations are predominantly present in moderate (100%) and severe (92.3%) ARDS.ConclusionLUS in the initial assessment of patients' with ARDS yielded significant findings in the three clinically designated categories. This study opens up the possibility of using POCUS as an adjunct in the initial assessment of ARDS patient in the ED.Copyright: © 2019 Journal of Emergencies, Trauma, and Shock.
